JOHN HENRY EICKERSHOFF, OF CINCINNATI, OHIO.

AUTOMATIC PRINTING AND ADDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 565,337, dated August 4, 1896.

Application filed February 26, 1896. Serial No 580,886. (No model.)

To aZZ whom it may concern;

Be it known that I, J OHN HENRY EICKER- SHOFF, a citizen of the United States of America, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Printing and Automatic-Adding Machines, of which the following is a specification.

The object of my invention is to provide a writing and automatic-adding machine in which the numbers are written in regular order from left to right and the addition accomplished simultaneously with the printing, a machine in which numbers of different de nomination may be readily written in columns and the result of any addition or partial addition indicated, and a machine in which add ing is accurately and positively accomplished and my invention consists in the combination and arrangements of parts hereinafter described and claimed.

Figure 1 is a front elevation of my device. Fig. 2 is a central vertical section; Fig. 3, a sectional plan of the device; Fig. 4, a top plan on a reduced scale; Fig. 5, a partial section of the position-key; Fig. 6, a side view of the same; Fig. 7, a detail elevation of the adding-wheels; Fig. 8, aplan of the same, and Fig. 9 an end elevation of the carriage.

Mounted in a casing A is a series of levers a, provided at their outer ends with fingerkeys a, preferably near the bottom of the casing. A series of levers of are pivoted on a shaft at a a and each is connected with one of the levers a by a link a Links at connect with a set of levers a carrying type a", adapted to print upon a record-strip. The other end of levers a are provided with pawls a adapted to operate ratchet-wheels B. The lengths of the arms of levers a, carrying links 0, vary according to the numeral to be printed. The greater the n umeral the shorter the lever. If, for instance, the key carrying figure 9 is pressed down, the catch corresponding therewith will rotate the ratchetwheels B to the extent of nine teeth, or if the key carrying the figure 2 is pressed down the catch will rotate the ratchet-wheel to the extent of two teeth. The ratchet-wheels B are mounted on a shaft C, supported in and rotating in bearings c. Mounted upon the same shaft is a bevel-wheel c, meshing with and operating a bevel-wheel 0 adapted to actuate a shaft C, supported in bearings 0 On the lower end of shaft C a spur-pinion c is mounted and adapted to engage with and operate a central wheel D, rotating freely upon a stationary upright stud d.

Meshing with and arranged about the periphery of wheel is a series of small wheels 6, rotating freely on upright spindles E, supported in and adapted to rotate in bearin gs 0'. It might be here mentioned that wheels 6 have. ten teeth, and the gearing between wheels 6 and ratchets B is such that by rotation of the ratchet-wheels B, say, nine teeth the wheels 6 are also rotated nine teeth.

Mounted on spindles E, above the wheels 6, are clutches e rotating with and adapted to slide on spindles E and engaging with wheels e. A set of shifting-levers F, adapted to engage with clutches e is pivoted to the casing at f and provided at their inner ends with guides f, adapted to support them against lateral movement. Spiral springs f secured to the shifting-levers and to plate f mounted above the shifting-levers, are adapted to return the levers F and clutches e to their normal position out of engagement with wheels e.

The extreme upper ends of spindles E are provided with arrows 9, adapted to register with a series of indicating-dials. By moving keys at the levers a and a, the catches a and the ratchet-wheels B, together with shaft C, are actuated, and this movement is transmitted by bevel-wheels c and c to shaft 0, thence by spur-pinion c to the central wheel D, from whence the rotation is transmitted to the small wheels e, ordinarily rotating freely. around the spindles E. By operating shifting-levers F wheels 6 transmit their rotation to spindles E and the arrows g.

Aposition-key, consisting, substantially, of a finger-key H, a spindle I, abell-crank lever K, and a shaft M, is mounted in casing A, and is adapted to operate shifting-levers F through a train of connecting mechanism hereinafter described. Key H is provided with a pin h, loosely fitted in a sleeve or socket Lin the spindle I. The upper end of spindle I is provided with a key 1', engaging with a bushing i embracing the socketed portion of spindle I, and passes through the top plate of easing -A. A collar i embraces bushing i below the top plate of easing A and supports the bushing against sliding movement. A handle 2'" is carried by bushing 2' adapted to rotate the bushing and, through the bushing, the spindle I.

A bell-crank lever K, pivoted to the casing at carries a fork 79 taking between a pair of collars on spindle I, and a pawl 7a for the operation of the ratchet-wheel L, secured to the shaft M, carried in bearings m. A sprocket-wheel m is also secured to shaft M, and is adapted to operate, through a chain connection, a second sprocket-wheel N, secured to a shaft or and supported in bearings 11. A bevel-wheel O is secured to shaft n and is adapted to engage with and operate a bevel-wheel O, secured to a sleeve P, surrounding and rotating freely on an upright shaft d. Above the wheel 0 is an arm 1), secured to the sleeve P, adapted to rotate therewith and actuate the lovers F. Surrounding the upper part of sleeve P is a bearing d, de pending from the top plate of easing A, adapted to support one end of sleeve P. The extreme upper end of the sleeve is provided with a pointer z.

Thelower part of spindle I is provided with a keyeseat 2', adapted to slide on a key carried by bevel-wheel i supported in a bearing i Meshing with bevel-wheel 1' is abevel-wheel i secured to shaft M next to ratchet-wheel L. By sliding spindle I the collar actuates the lever K, and pawl it operates the ratchetwheel, thereby rotating shaft M. Sprocketwheel m being rotated, the movement is transmitted to shaft N through a chain connection, and bevel-wheels O and O rotate sleeve P, arm 10, and pointer e. As the bevelwheel i is secured to shaft M, and is rotating therewith, the spindle I, in a sliding movement, also gives to itself a rotary movement. By turning handle i of the position-key a quick rotation of the parts operated from key II is possible. I

I do not wish to confine myself to the specific form of position-key and mechanism connecting it with the shifting-levers shown, as any transforming mechanism may be used without departing from the spirit of my invention, so long as but one transformer is used adapted to place any indicator in driving connection with any key. By this arrangement the actuation of a single key effects, by suitable connecting mechanism, all of the required changes of position of the pointer .2, the key and its connections constituting what will hereinafter be called a transformer.

S is a carriage provided with wheels S, a rack s, paper-storing roll T, paper-supporting roll Apaper-feeding roller 6, and friction-rollers i pad 15, and a set of carbon-strip rollers f. The feed-roller t is provided with a lever 21, having a catch a and a ratchet-wheel a Iivoted to the end of the feed-lever 'u is a rod a, guided at its lower end in a bracket 11 The lower end of red a is provided with a projection engaging with curved guides 11 when the carriage is actuated, thereby operating the feed-rolls. A gear-wheel R, partly blank, is secured to shaft M, adapted to cooperate with rack s and move the carriage.

By revolving the shaft M, as illustrated, wheel R is also rotated and the cogs of the wheel engage with rack 8 during the forward movement of the carriage and the printing of a line of figures. The rack is then released by the blank space of wheel R, and the carriage S is automatically returned by spring a and is ready for another forward movem ent. Spring a is secured to casin g A and provided with a cord a connected to the carriage S, and a pair of sheave-wheels a". A pair of stops Vare secured to the rails o to limit the return movement of the carriage.

Near the upper part of the indicator-spindles E, below bearings e, are secured gearwheels 9 adapted to engage with and actuate intermediate wheels 9 rotating freely on pins g. Each of the intermediate wheels 9 is provided with a pin or tooth g extending from the face thereof and adapted to engage with and actuate a gear-wheel g after a complete revolution of wheel and spindle E of the dial indicating the next higher denomination is moved to the extentof one tooth.

The top of the indicators G and the pointer e is covered with glass for protection. In the center of the glass covering the indicators are small holes to permit a key to enter keyholes in the arrows, which are adapted to return them to 0 upon the completion of the addition of a column of figures.

The operation is as follows: Before adding a column of figures return all the arrows of the indicators 7t to .O by using a key for the pointers of the indicators. Suppose now that two lines of figures, say 4028489 and 5107121, should be written and added. First take handle 7 of the position-key and turn so that the arrow is directed toward the million-indicator G, as the highest figure of the first line to be added is million. Corresponding and in same line with pointer is arm 1), operating the shifting-levers F with clutch e for connecting the same with wheels 6, in order to operate the spindles E and arrows 9 of million-indicator G. If, therefore, the pointer is set to the million-indicator, it means that arm 1) has connected lever F and its clutch with the wheel 6 of the million-indicator. The carriage containing the paper and printing-pad for printing the figures is corresponding with pointer z and also ready for printing the first figure in the millionline. Now push key 4:, and by this movement the figure a is printed on the record-strip, and the ratchet-wheels B are rotated four teeth, which movement is transmitted to the wheel 6, so that the indicator of million shows the figure a. Push now the position-key, which brings pointer .2 to the next indicator, hundred thousand, by which movement the carriage is also moved and ICC 'cator ten shows ready for the next figure. .The number wanted in hundred thousand is 6. Push figure 6 and this figure is printed on the paper next to at, and the indicator hundred thousand shows 6. Now the position-key is pushed again and the pointer 21 released from the cogs of wheel R and is returned by spring n By the return movement of the carriage, actuated by the spring, the feed-roller t is operated by the curved rods and by the other mechanism for the feedroller, as before described. By this means the record-strip is brought in position for the next line of figures. Now it will be necessary to have the machine speedily placed in position for the next line to be added, and in order to do so the handle '6 of the positionkey is turned, which operates the arm p. The handle 2' is turned until pointer 2 reaches the highest figure next to be added, which is in the present case again million. When pointer z is fixed for that place, the numberkey 5 is pushed, which figure is printed below the figure 4c of the first line. The million-indicator will now show 9, as the first figure was 4, and 5 is added. Now the position-key H has to be pushed for the next figure, after which the number-key l is pushed, indicating at hundred thousand 7, because the figure shown before on the indicator was 6, and 1 is added. The printing is going always the same as before. Push position-key again for ten thousand, and then figure-key O. This figure has no connection with any part of the indicators, and is only printed, and it is therefore not shown on the indicator. The 'next figure is 7 for column thousand. The figure before recorded on that indicator was 8, and by addingthe 7 the figure F is obtained, and by the adding-wheels the figure 1 is transmitted to the next higher indicator, in this case to the ten-thousand indicator, which transferring is done automatically as soon as the arrow of the thousand indicator passes between the figures 9 to 0. The operation is done by the gear-wheels g and intermediate wheels 9 and the pin or tooth 9 as described before. The next figure now to be added is 1 in the hundred indicator. The figure recorded here before was 4,and by adding 1 the figure 5 will be recorded. The next figure now will be 2, and as the indicator ten shows 8 it will be necessary to transfer the figure l to the hundred indicator, making it read 6, and the indi- The last figure in the line to be added is 1, and as that indicator shows 9 it will show after adding the 1 the figure 0, as figure 1 has to be transferred to the ten indicator, which was indicating 0, but after the adding will record 1. Reading now the indicators it will be found that they read as follows, commencing with the indicator on the left side, 9735610, which is the sum of the two lines of figures added. After the last figure is added the carriage automatically returns. The arrow .2' is now moved from the last indicator, so as to disengage arm 19 from levers F, so that the carriage S is free from the cogs of wheel R. Then the carriage is moved by hand to make a line of dashes below the figures to be added, thus leaving the indicators unchanged. The carriage is then moved by hand for printing the figures below the dashes as they appear on the indicators.
